Granite :)
Granite is a coarse grained igneous rock without Pyroxene.
A peridotite is a dense, coarse-grained igneous rock
There are many. A great example, however, is Mt. Rushmore; the likenesses of the presidents are carved in granite, a coarse-grained intrusive igneous rock.

Yes. Exactly, they do have both, fine grained and coarse grained rocks.

A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.

Granite is an example of an intrusive igneous rock. It forms from the cooling and solidification of magma beneath the Earth's surface, resulting in a coarse-grained rock with interlocking mineral crystals.
Methods of formation. If crystalline (igneous or metamorphic) they would most likely have had differing rates of cooling. If sedimentary, they would most likely have had differing depositional environments (higher energy for larger grain sizes).
